Observations of IC458

These are the observations available for IC458. If you have any of your own that you'd like to submit we'd love to put them on the website.

• IC Galaxies around NGC 2340

  On you Webb Society web site you talk about NGC 2340 and the other nearby galaxies. Then you ask for some input. I checked my old observations and I will give them below. I did not include the two brighter galaxies NGC 2332 & 2340.

  IC 458

  3/28/87 17.5" 12mm

  Seen w/ direct vision, roundish, diffuse, similar in size & slightly fainter than IC 464, brighter than IC 461, star very close to southern tip.

  3/16/91 12.5" 12mm

  Direct vision, roundish, diffuse, star on southern tip.

  1/10/2000 12.5" 12mm

  AV/1, slightly ellip, diffuse, even brightness throughout, star on southern tip.

  IC 459

  3/28/87 17.5" 12mm

  NOT SEEN

  IC 460

  3/28/87 17.5" 12mm

  AV/1 best, appears almost star-like, very faint thin diffuseness surrounds a brighter very compact core.

  1/10/2000 12.5" 12mm

  AV/2, very close to a star on it's NP edge which tends to "wash out" this galaxy. It is small, round, diffuse, even brightness throughout.

  IC 461

  3/28/87 17.5" 12mm

  AV/1, very diffuse patch of light, even brightness throughout. There is a faint star following which is brighter than the galaxy.

  IC 464

  3/28/87 17.5" 12mm, 10mm.

  12mm= Direct Vision, elliptical, possibly very gradually brighter towards the middle. 10mm= I now see a very compact little brighter core.

  3/16/91 12.5" 12mm

  Direct vision but faint, roundish, diffuse, brighter very compact core.

  1/10/2000 12.5" 16mm

  While observing NGC 2340 I soon noticed IC 464 in my field. It was seen with AV/1, a little elliptical shaped, diffuse, very small, patch of light, has a slightly brighter star-like core which "comes & goes".

  IC 465

  3/28/87 17.5" 12mm

  Direct Vision, slightly elliptical, diffuse, even brightness throughout, about the same size as IC 464 but slightly brighter.

  3/16/91 12.5" 12mm

  AV/1, small, round, diffuse envelope surrounds a slightly brighter star-like core.

• Lots of galaxies near NGC 2340

  Dale Holt was quick out of the blocks with a sketch of this month's galaxy, NGC 2340, observing the field on 2 February 2016! He then sent the resulting sketch to Owen Brazell with this note.

  Dale's Comments

  I managed to get a look at your recommended galaxy grp in Lynx last night, sky was very hazy when I made my observation around midnight. My fov is rather small so I didn't get the whole group in but I managed to pull out 11 galaxies in total, some very small and quite faint.

  Good fun so thank you for the challenge.

  Kind regards, Dale

  

  I hope that Dale doesn't mind, but I flipped his sketch vertically to match the orientation of the Digitised Sky Survey (DSS) field I've added to the right. When comparing the two I'd be quite pleased with that result, well done Dale.

  Please click on Dale's sketch to see the original.

  Owen's Response

  Dale had noted that he hadn't been able to identify the galaxies other than NGC 2340 in the sketch yet, and Owen obliged with this chart (click on it for the version you can read!) and some comments.

  

  Hm OK Of the main galaxies I think you have NGC 2340, IC 464, IC 458, IC 459 and IC 460. The others are too faint to be in the NGC or IC. This is probably the best chart I can make for your field.
